4 Claims.

This invention relates in general to drain and waste traps, and moreparticularly to improved means for mounting the same in concrete, or thelike.

A principal object of the invention is the provision of simplified meansfor forming a rigid connection between a drain or waste trap, or thelike, and concrete, or the like, in which it is embedded.

Another important object of the invention is the provision of suchconnecting means which comprise lateral extensions forming a part of thecasing of the trap and flexible members interconnecting the extensionsand the usual reinforcing means employed in the concrete Within whichthe trap is embedded.

A further important object is the provision of such connecting meanswhich enable a trap to be satisfactorily embedded either in an aperturein preformed concrete or in concrete which is laid subsequent to thepositioning of the trap, and which will rigidly secure the trap to theconcrete to'effectively prevent breaking away of the concrete therefrom.

Another important object of the invention is the provision of simplifiedmeans for effecting a leak-proof connection or joint between a drain orwaste trap, or the like, and concrete, or the like, in which it isembedded.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, whentaken in connection with the accompanying drawing, discloses a preferredembodiment thereof.

In the drawing,

Figure 1 is a perspective view of a device embodying the features of theinvention, with parts broken away and parts in section; and

Figure 2 is a top plan view of the device of Fig. 1, with part of theconcrete broken away, showing a slight modification in the connectingmeans.

Referring more particularly to the drawing, reference numeral I Iindicates in general a drain or waste trap which comprises a unitarycasing I2, having an outlet connection I3 formed integrally therewith,and a removable grating or open cover member I4 for the casing. The trapII is similar to those disclosed in my prior Patents No. 1,959,623,issued May 24, 1934, and

No. 2,099,061, issued November 16, 1937. Since I the interiorconstruction of such a trap does not form a part of the subject matterof this invention, reference is made to these patents for the detailsthereof A drain or waste trap of this type is adapted to be mounted in asuitable recess in a floor for the purpose of receiving water, greaseand oils which may accumulate on the floor, such as in a garage, or thelike. In prior installations of such traps, great difficulty has beenencountered in providing a leak-proof joint between the floor and thetrap and in preventing those portions of'the floor, especially if thelatter is of concrete construction, adjacent to the trap from crackingand breaking away. The instant invention is adapted to simply andreadily overcome these difliculties. I

In Fig. 1, reference numeral I5 indicates in general a concrete floor ofany suitable construction within which it is desired to embed the trapII. The concrete floor I5 is provided with the usual wire meshreinforcing I6. The casing II! of the trap II is provided exteriorlythereof with a plurality of outwardly extending lugs or flanges I! whichare preferably formed integrally therewith. In the preferred embodiment,these lugs I II are spaced around the periphery of the casing I2, butthe invention is not intended to be limited to any particular form,shape or construction of these members. Each of the-lugs I1 is providedwith a vertically disposed aperture I8 extending therethrough.

In Fig. 1, the trap I I is shown as being mounted or embedded in a newconcrete floor. That is, the trap II is first suitably positioned, andthen the concrete is'poured to form the floor I5. In this particularinstallation, it is a relatively simple matter to cut away a portion ofthe floor. reinforcing I6 or so lay the latter as to provide an aperturetherein, the dimensions of which will substantially coincide with thoseof the casing I2. The trap II is then positioned in this aperture in thereinforcing I6, or the reinforcing is disposed around the trapafter ithas been suitably mounted in desired position. The lugs I1 are thenrigidly secured to the flooring reinforcing I6-- by means of flexiblewires or the like I9 (Fig. l) The apertures I8 in the lug I1 willfacilitate such tying of the reinforcing I6 thereto.

After the trap II has been thus rigidly secured to the flooringreinforcing I6, theconcrete is poured in the usual manner to form thefloor I5.

this way, the concrete floor I5 will be effectively prevented fromcracking or breaking away djacent the trap I I, and the latter will berigidly =5 secured to the floor to provide what is in substance aunitary structure.

Since it may well be that a relatively narrow space will be left betweenthe casing I2 of the trap I I and the adjacent portions of the concretefloor I5 after the latter has hardened, due to the usual shrinkageattendant therewith, it may become necessary to so fill this space as toprovide a leakproof joint between the trap and the adjacent upperportions of the floor. The invention contemplates the filling of thisspace with any suitable material, asindicated by reference .numer-al 2|,that will function to attain the desired purpose. For example, thematerial 2I may comprise lead, solder, or other suitable material whichhas been poured into this intervening space.

Likewise, oakum, tar, or any other suitable filling or calking materialmay be used for this purpose.

It will be seen that the resulting structure attains the desiredfunctions of rigidly securing the trap I I to the floor I5, effectivelypreventing cracking and breaking away of those portions of the floordirectly adjacent to the trap, and providing a leakproof joint betweenthe trap and the floor at the upper surface thereof.

In Fig. 2, the trap I I is shown as being mounted or embedded in apre-formed concrete floor, indicated generally by reference numeral 22.The floor 22 is substantially similar in all respects-to the fioor I5above described, except that-it is one which has been constructed priorto the installation of the trap II. I I in this pre-formed concretefloor 22, which includes the usual reinforcing material 23 which issimilar to the reinforcing IS, an aperture of suit able dimensions isprovided by breaking away the concrete and reinforcing in any desiredmanner. In Fig. 2, this aperture is indicated by reference numeral '24,and is shown as being much larger than is necessary, for the purpose. ofillustrating the manner of securing the trap to the floor which isslightly different than that above described relative to themodification of Fig. 1.

After the aperture 24 has been formed in the concrete floor 22, thatportion of the reinforcing 23 which remains extending into the apertureis straightened as much as possible and is cut away, if necessary, toprovide suflicient clearance to permit the trap II being properlypositioned therein. The trap II is then secured to the reinforcing .23by means of flexible members 25,

preferablyin the form of metal wire or the like,

which are threaded through the apertures IS in the lugs 'I I and woventhrough the reinforcing 23. In Fig. 2, one member 24 is shown associatedwith each of the lugs II, but it is quite apparent that any desirednumber of these members may be employed and that the weaving or In orderto embed the trap intended to be limited to the particular trap shown inthe drawing. Similarly, it may well be employed in securing a trap in adifferent type of floor than that herein illustrated, or in any otherdesired type of supporting structure.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that .various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

I claim:

1. The combination of a trap, a supporting structure surrounding saidtrap and having reinforcing means forming a part thereof, means securedto said trap and extending into said supporting structure, and meanssecuring said last means to said reinforcing means.

2.In combination with a waste trap, or the like, ,a supporting structuresurrounding said trap and having reinforcing means disposed interiorlythereof, and means rigidly securing said trap ,to .said supportingstructure, comprising means secured to said trap, and means securingsaid last means to said reinforcing means.

.3. The combination of a concrete floor structure having reinforcingmeans therein, with a trap embedded in said floor structure, extensionsformed on said trap and extending exteriorly therefrom, and meanssecuring said extensions to said reinforcing means.

4. In combination with a waste trap, or the like, a supporting structuresurrounding said trap and having reinforcing means disposed interiorlythereof, and means for rigidly securing said trap to said supportingstructure, comprising outwardly extending lugs formed integrally withsaid trap, and flexible members securing said lugs to said reinforcingmeans.
